TDM-pumped RFA Assisted Transmission of 20x10 GE Channels over 364 km in a Three Span Link

We present experimental results on application of time-division multiplexed (TDM) pumping in a transmission of twenty 10 GE channels over 364km long fiber link. The link is composed of 3 spans mixing 264 km of non-zero dispersion shifted (NZ DSF) and 100km of conventional single-mode fiber (SSMF). Distributed Ram-an amplification in the 3 fiber spans is realized by counter-directional TDM pumping and assisted by booster EDFA and EDFA preamplifier. Error free transmission is checked by measuring bit error ratio.
